Problem With Synthetic Estimates

Nationally, modelled or synthetic estimates of the prevalence of lifestyle risk factors, and models are available to estimate the prevalence of various diseases in different populations. A modelled or synthetic estimate is only as good as the model and as good as the underlying data from which the model is produced. A full discussion of the Problem of Synthetic Estimates (2 pages) is available.
